Abstract: A jewelry design including a mounting made of a precious jewelry metal, a plurality of fluorescent diamonds having at least medium blue fluorescent intensity which are set in the mounting to form a message, and a plurality of non fluorescent diamonds set within the mounting adjacent the fluorescent diamonds, such that when the mounting is viewed under standard light the fluorescent diamonds are not discernable from the non fluorescent diamonds and the message is not visible, and such that when the mounting is viewed under ultraviolet light the fluorescent diamonds emit visible blue light to form and reveal the message.

Abstract: A separable plastic male-to-male connector includes a pair of connector units each having a planar base and a plurality of protrusions extending outward from the base and being oriented on the base so as to form a matrix. The matrix has a plurality of lateral and longitudinal rows wherein a distance C.sub.L1 is between centers of laterally adjacent male protrusions, and wherein a distance C.sub.L2 is between centers of longitudinally adjacent male protrusions. Each protrusion includes a head portion and a stem portion. The head portion has a height K.sub.H equal to 0.50*(C.sub.L1 +C.sub.L2)/2 and a diameter K.sub.D equal to 0.75*(C.sub.L1 +C.sub.L2)/2. The stem portion has a first end attached to the base and a second opposed end attached to the head portion. The stem portion has a height S.sub.H equal to 0.63*(C.sub.L1 +C.sub.L2)/2 and a diameter S.sub.D equal to 0.56*(C.sub.L1 +C.sub.L2)/2. C.sub.L1, C.sub.L2, K.sub.H, K.sub.D, S.sub.H, and S.sub.D each have a tolerance of .+-.6%.

Abstract: An exercise apparatus which isometrically works the upper body muscles while the person is engaged in an aerobic activity such as walking or while the person remains in a standing or sitting stationary position. The exercise apparatus includes a belt member having a first end, a second end, and a body section disposed between the first and second ends. The first and second ends are securable to each other for fastening the belt member around the torso of a person. A pulley housing is mounted to the body section of the belt. A pulley wheel is rotatably mounted within the pulley housing. An adjustable tension mechanism is attached to the pulley housing and the pulley wheel for selectively adjusting an amount of force needed to rotate the pulley wheel within the pulley housing.
